display multicast-vlan ipv6

Syntax

display multicast-vlan ipv6 [ vlan-id ] [ | { begin | exclude | include } regular-expression ]

View

Any view

Default level

1: Monitor level

Parameters

vlan-id: VLAN ID of an IPv6 multicast VLAN, in the range of 1 to 4094. If this argument is not provided, the information about all IPv6 multicast VLANs will be displayed.

|: Filters command output by specifying a regular expression. For more information about regular expressions, see Fundamentals Configuration Guide.

begin: Displays the first line that matches the specified regular expression and all lines that follow.

exclude: Displays all lines that do not match the specified regular expression.

include: Displays all lines that match the specified regular expression.

regular-expression: Specifies a regular expression, a case-sensitive string of 1 to 256 characters.

Description

Use the display multicast-vlan ipv6 command to view information about the specified IPv6 multicast VLAN.

Examples

# View information about IPv6 multicast VLANs.

<Sysname> display multicast-vlan ipv6

 Total 1 IPv6 multicast-vlan(s)

 

 IPv6 Multicast vlan 100

   subvlan list:

    vlan 2  4-6

Table 1 Output description

Field

Description

Total 1 IPv6 multicast-vlan(s)

Total number of IPv6 multicast VLANs

IPv6 Multicast vlan

An IPv6 multicast VLAN

subvlan list

List of sub-VLANs of the IPv6 multicast VLAN

 

multicast-vlan ipv6

Syntax

multicast-vlan ipv6 vlan-id

undo multicast-vlan ipv6 { all | vlan-id }

View

System view

Default level

2: System level

Parameters

vlan-id: Specifies a VLAN by its ID, in the range of 1 to 4094.

All: Clears all IPv6 multicast VLANs.

Description

Use the multicast-vlan ipv6 command to configure the specified VLAN as an IPv6 multicast VLAN and enter IPv6 multicast VLAN view.

Use the undo multicast-vlan ipv6 command to remove the specified VLAN as an IPv6 multicast VLAN.

By default, no VLAN is an IPv6 multicast VLAN.

The specified VLAN to be configured as an IPv6 multicast VLAN must exist.

You cannot enable IPv6 multicast VLAN on a device with IPv6 multicast routing enabled in the public instance or VPN instance.

MLD snooping must be enabled in the multicast VLAN before the IPv6 multicast VLAN feature can be implemented, while it is not necessary to enable MLD snooping in the sub-VLANs of the IPv6 multicast VLAN.

Related commands: mld-snooping enable and multicast ipv6 routing-enable.

Examples

# Enable MLD snooping in VLAN 100, configure it as an IPv6 multicast VLAN, and enter IPv6 multicast VLAN view.

<Sysname> system-view

[Sysname] mld-snooping

[Sysname-mld-snooping] quit

[Sysname] vlan 100

[Sysname-vlan100] mld-snooping enable

[Sysname-vlan100] quit

[Sysname] multicast-vlan ipv6 100

[Sysname-ipv6-mvlan-100]

multicast-vlan ipv6 entry-limit

Syntax

multicast-vlan ipv6 entry-limit limit

undo multicast-vlan ipv6 entry-limit

View

System view

Default level

2: System level

Parameters

limit: Maximum number of entries in the MLD snooping forwarding table of IPv6 multicast VLANs. The value ranges from 0 to 1024.

Description

Use the multicast-vlan ipv6 entry-limit command to configure the maximum number of MLD snooping forwarding entries of IPv6 multicast VLANs.

Use the undo multicast-vlan ipv6 entry-limit command to restore the default.

By default, the upper limit is 1024.

Related commands: entry-limit.

Examples

# Configure the MLD snooping forwarding table of the IPv6 multicast VLANs to contain 512 entries at most.

<Sysname> system-view

[Sysname] multicast-vlan ipv6 entry-limit 512

subvlan (IPv6 multicast VLAN view)

Syntax

subvlan vlan-list

undo subvlan { all | vlan-list }

View

IPv6 multicast VLAN view

Default level

2: System level

Parameters

vlan-list: Defines one or multiple VLANs as sub-VLANs. You can provide up to 10 VLAN lists, by each of which you can specify an individual VLAN in the form of vlan-id, or a VLAN range in the form of start-vlan-id to end-vlan-id, where the end VLAN ID must be greater than the start VLAN ID. The value range of a VLAN ID is 1 to 4094.

all: Removes all sub-VLANs of the current IPv6 multicast VLAN.

Description

Use the subvlan command to configure sub-VLAN(s) for the current IPv6 multicast VLAN.

Use the undo multicast-vlan ipv6 subvlan command to remove the specified sub-VLAN(s) from the current IPv6 multicast VLAN.

By default, an IPv6 multicast VLAN has no sub-VLANs.

The VLANs to be configured as the sub-VLANs of the IPv6 multicast VLAN must exist and must not be IPv6 multicast VLANs or sub-VLANs of another IPv6 multicast VLAN.

Examples

# Configure VLANs 10 through 15 as sub-VLANs of IPv6 multicast VLAN 100.

<Sysname> system-view

[Sysname] multicast-vlan ipv6 100

[Sysname-ipv6-mvlan-100] subvlan 10 to 15
